Haggai, Zechariah, and Malachi are Postexilic prophets....they speak AFTER the people have been allowed to return from their Babylonian Exile.
Haggai: c.520BC - Though the people have returned, they have NOT rebuilt the Temple, partly due to outside influences, but also lack of proper priorities. See
Ezra 1-6 for background. Does God have priority in your life?
Zechariah: c.520BC (Same as Haggai above.) Chs1-4.... Return to God, there will be a New Jerusalem, we are the apple of God’s eye! We can have Hope!
